Work around glslang issue 988

The basic bug there is that if you have a member of `struct` type in a `uniform` block and then pass a reference to that member directly to a call:

```
struct Foo { vec4 bar; };
uniform U { Foo foo; };

void main() { doSomething(foo); }
```

then glslang generates invalid SPIR-V which seems to cause an issue for some drivers.

This change works around the problem by detecting cases where an argument to a function call is a reference to `uniform` block member (of `struct` type) and then rewrites the code to move that value to a temporary before the call.
